Applications
The BLUE ECO pump was designed for fresh-, brackish- or salt water, or other low viscosity liquids which are neither
explosive nor aggressive or oily. The pump may be used for clean water and in a limited way also for contaminated water.
The pump is not intended for water with coarse debris. Particles should not be larger than 0.8 mm. Basically the pump is
intended for use with „clean water” without solid particles which may damage the bearings, like, for example sand and
pyrolusite after the treatment of ponds with potassium permanganate. Warranty does not apply for damages resulting from
above described particles. The bearings of the pump are milled spirally to evacuate particles larger than 0.8 mm. The
bearing plate contains enough space for a filter. The filter must be cleaned regularly regardless the degree of soiling. A
special amount of water is flushing the pump housing to ensure long term operation of the pump. To decrease the flow rate
in the housing, perfectly close the plate and adjust to the smallest dot on the plate. Now the bearing lubrication by water is
very low.
The BLUE ECO Pump is generally used for filter systems of ponds or pools and /or for brooks and cascades. The pump is
not self-priming, so for use above the water surface a check valve must be installed to the pump’s inlet. In this case the
pump must be water filled before operation.

Model identification: The Blue Eco 240 and 320 Watt use the same model pump, the controllers are different. This means
that a model 240 can be controlled by a 320 watt controller and vice versa. The type plate of the 320 shows a 500
indication box (at the time of production there was no 320 model available). Model 500 uses the same pump as model 900.
The controller determines the model. In the future you can decide to buy a 320 controller for a model 240 or a 900
controller for a 500.
Noise emission:
The noise emission of the pump is within the limits of the machine guidelines of the European Council.
Important
Initial use of the BLUE ECO pump 240 watt & 320 watt.
When using the pump for the first time please use the following steps:
The blue Eco pumps use a flexible O-ring between the impeller and the pump house to obtain a optimum seal for
maximum efficiency. This sealing ring must “run in” (under water!) for a while. When you switch the pump on for the first
time you will see that at 1000 RPM (factory default setting) the power consumption is about 50 watt. Depending on the
circumstances this will go back to about 25 watt in the next 1 to 24 hours. After that the pump is completely run in . A
wrong setting operation cannot harm the pump. Every box comes with a bag of spare O-rings. When you have removed
the impeller from the shaft you need to put in a new O-ring when re-installing the impeller.

Short Instruction
The pump is driven by a DC-motor and, therefore, equipped with a controller. Check the following sequence when starting
the pump:
1.) Flush the pump thoroughly to remove any residual disinfection fluids!!!
2.) Install the pump below the water surface (Pump is not self-priming).
3.) Interconnect pump and controller using the attached controller cable (check pins).
4.) Check the main power switch is set to „0” (OFF).
5.) Connect the mains cable to the controller and plug into a wall plug.
6.) Switch on the controllers power switch. The pump will run immediately! (after a 10 second delay)

Switching the pump on and off:
The pump is switched on and off with the „0/1“-switch.
After switching on there is a 10 second delay countdown. After that, the pump slowly increases speed to the previous value
set, while the flow rate is also updated.
When switched off, the pump stops immediately.
▲ / ▼ keys:
Use the ▲ / ▼ to set the power of the pump.
This will also change the flow (l/h) and the energy consumption (W) and the RPM.
The power can be set between 10 and 240/320/500 watt (depending on the model).
The pump will always run on the set power.
After a power break the pump will automatically return to the last setting.

INSTALLING
If used in dirty water the pump requires a pre-filter as mentioned earlier
in the manual. We recommend the use of 2- or 3/3 unions, for easy
disassembly for pump cleaning or maintenance.
Example 1
Suction side: 2-part unions with rubber ring for easy sealing (art.nr.
AG287: 2½” x 63mm, see picture). Pressure side: a PVC 3 part Union
(Ø63mm) can be glued on the pressure side. Do not glue straight
socket fittings on the pump as this makes disassembly extremely
complicated! The use of pieces of flexible is recommended to prevent
vibration and resonation. (see example 2).
Model 240/320
Example 2: Flexible fittings provide a vibration free
performance and are very easy to remove. Suction side: a
solvent ring 90mm x 2½” fem. thr. (art.nr. AB367) can be fitted
with some liquid Loctite 5331 (art.nr. AK142) or Teflon tape.
On this ring a flexible reducer fitting (90mm/3” to 63mm/2”)
can be fitted (art.nr. FC146). On the pressure side you can
put a 63mm/2” flexible fitting (straight socket “FC122” or a 90°
bend “FC172”). The rubber feet underneath the pump will
provide a complete vibration free performance.
Example 3: Model 500 has a double suction side:
110mm outer diameter and 2½’ male threading.
You can use a flexible socket for the 110mm
connection (art.nr. FC128). For the threaded
connection you can use a 2-part unions with rubber
ring for easy sealing (art.nr. AG287: 2½” x 63mm)
For de pressure side you can use a 3/3 PVC union
Ø63mm x 2½” fem. thr. (art.nr. AB246) with teflon
or Loctite 5331 (art.nr. AK142).

Assembly
Attention:
Read the manual carefully before installation of the pump. Damages resulting from non-observance are not covered by
warranty.
When unpacking the pump, check the parts for completeness and damages. Damages detected must be advised to the
supplier within 8 days after purchase. It is possible that the pump is moist or wet after unpacking due to the fact that the
pump had been tested before leaving the manufacturer. Before wrapping, the pump has been treated with a biodegradable
disinfectant to eliminate possibly existing germicides. Therefore the pump must be rinsed thoroughly before operation.
Check the pump for damage before putting into operation. A damaged pump must NOT be operated. Immediately contact
your supplier! Putting the pump into operation in spite of visible damages will void warranty and manufacturers liability.
Unplug the pump from the mains and make sure it cannot be operated. The pump must not be connected to the mains
during the entire installation process. Never put your hands or fingers into the openings of the powered pump to prevent
injuries.
1.1.
Controller
The controller unit can be installed indoor and outdoor. Do not expose the controller to direct sun light or heat (powerful
lamp, radiator). Be sure there is enough air circulation. Keep all sides of the unit free for at least 10cm.

1.2.
Pump
The pump must be installed in a horizontal position. The pump must rest firmly on a flat and even surface. Install the
intake line to the pump’s inlet (1) (see fig.). Make sure the pump can evacuate air from the outlet (2). At best, install the
pump below the water level (3). The pump may be installed inside (4) as well as outside (dry) of the water (5). If operated
outside, check for sufficient air circulation. Do not expose the pump to direct sunlight. Install the pump as close as possible
to the location of water withdrawal, i. e. the intake line should be as short as possible. If the pump was operated above the
water level (6) install a check valve to the pump’s inlet (7). In this case, the intake line of the pump must be filled with
water. This kind of installation exposes the pump to dry run damages if the check valve doesn’t work correctly. Damages
resulting from running dry are not covered by warranty.

1.3.
Suction side (pump inlet)
If there is not enough water, due to the resistance of the intake line the pump needs a lot of power and the electronics will
heat up in the long run. The electronic circuit protects itself by powering down. If the flow rate of the pump decreases within
a couple of hours or days, the reason might be the too high resistance of the intake line, especially on warm days.
Try to enlarge the pipe diameter after the pump to a sufficient size for more pump capacity and and lower energy
consumption.
It is not allowed to let the pump run dry. It will lead to irreparable damage to the shaft and silicium carbide bearings.
Especially when the pump is mounted above the water surface level (with a check valve) you have to be very careful about
8
this. When used in dirty water the use of a (previously described) pre-filter is necessary. The use of flexible fittings or
unions is recommended for easy dismantling for cleaning and/or maintenance.
The pipe work must be fitted in a way that possible mechanical stress (due to changing temperatures) have no negative
influence on the pump house. Any tubing on the intake line must be 100% air tight. If a hose was used as intake line, make
sure the hose is in accordance to the requirements for intake hoses. It is very important that the intake line on the pump
head is primarily straight (min. 5 times the diameter of the inlet). This will increase the power of the pump, due to the
laminar water flow on the impeller. Avoid short 90° bends, try to use long swept bends (less pressure loss).

If the intake line is longer than 10 meters or the intake height is higher than 1 meter, the diameter of the intake line must be

1.4.
Pressure side (pump outlet)
The pressure side must be at least the same diameter like the diameter of the pump’s outlet to avoid pressure drop, too
high flow rates and noise to a minimum. At best increase the diameter of the tubing directly behind the pump to increase
flow rate and save energy.

Electrical connections– initial startup
Compare voltage and frequency imprinted on the specification plate to the specifications of your mains voltage. The one
who is responsible for the installation must check, if the voltage grounding was according to specifications. It’s also
important to check, if the installation was secured by a sensitive fault current detection switch (30mA - DIN VDE
0100T739). The mains fuses should be stronger than the pump fuses.

Maintenance
Unplug the pump before maintenance. Blue Eco series are basically treated as low maintenance. In normal case
maintenance is restricted to impeller checking for clogging. Remove potential objects from the impeller with a thin, spiky
tool. A reduced delivery rate of the pump is generally caused by waste in the impeller. In the case of calcification
(especially when used in salt water) remove the scale with a weak acid like vinegar. Avoid sidewise pressure to the
impeller or the rotor. The pump can be completely disassembled for cleaning. The rear bearing can be easily removed by
unscrewing of the bearing plate counter clockwise. Use an appropriate tool to move the shaft to the front, so the impeller
unit can be removed much easier. In fresh water applications, calcification generally occurs before and after a complete
pond filling. The dissolved lime scale will precipitate within 2 or 3 days.
Use a M6-Allan key to remove the titanium screws (1), which mount the pump head to the motor housing. Now, the
complete pump head can be removed. If necessary, remove the complete impeller from the 240/320 unit by pulling out the
shaft after removing the O-ring. For the models 500/900/1500 you need to remove the nut on the impellers front. This will
reveal 3 screws that also need to be removed. You can now remove the shaft.
!
Be very careful, because the impeller is fixed to its position by a strong magnet. Releasing the shaft occasionally may hit
the bearing resulting in severe damage. Do not underestimate the power of the magnets. If you lose grip the shaft
will hit the rear bearing, which most likely will result in severe damage and, thus, in expensive repair costs...
12
After maintenance reassemble the pump in reverse order. Do not over tighten the screws, due to the fact that the threads
in the case are made from plastic. The O-rings are made from silicone or EPDM/Viton, depending on the application. As
spare parts, only use new and original O-rings with the proper thickness and hardness. Used O-rings slowly alter their
hardness. Always replace with new parts if disassembled to prolong the life time of the pump. Silicone and EPDM/Viton ORings are resistant against acids and bases.
Bearings
The bearings of the 240 and 320 are based on silicium/ carbide (the hardest material after diamond). The front and back
bearing are equal and can be switched. At normal use they will last for life. Both bearings sit in a EPDM O-ring that will
adsorb vibrations and keep the bearing in a exact position. The shaft of the 240/320 is made of wolfram and also acts as a
bearing. The 500/900/1500 Watt model have a flat silicium carbide slip bearing that will keep up with the axial and radial
forces. These bearings are exchangeable. These bearings are based on a wet sealant that means that the pump has no
seals that can leak. The shafts of the 240/320 watt are made of an improved wolfram that is seawater resistant. The shafts
of the 500/900/1500 Watt are made of 100% pure titanium of the highest class G5.
Power outage + auxiliary power supply
After a power out the pump automatically restarts itself and the controller resets to the speed previously set.
The pump can be with a common auxiliary power supply, when equipped with a rectifier. The pump can be used with a
common UPS, when equipped with a rectifier.
